Abstract
Generally, the deterioration characteristics of a conductor affected by a forest fire can be analyzed through simulation of a forest fire and results of the simulation. However, there are little accomplishments of that kind of simulation applied to the power transmission, and there aren't actual analysis for a sample exposed in a forest fire. This paper deals with the experimental results that apply to a new wire by an artificial flame equipment because it's difficult to directly analyze the characteristic by a forest fire. Also, after an artificial flame is applied to a normal ACSR for various experimental conditions, changes of mechanical and material characteristics of the ACSR were analyzed by the surface inspection and load-tests of tensile of the ACSR. Then, the database will be made to made to predict the state of deteriorated wires by a forest fire using those two data, and data necessary to diagnose the life state of an ACSR wire affected by a forest fire will be given.
